CICADELLINAE: PART 2. NEW WORLD CICADELLINI Lei 
_ third, without an anteapical plexus of veins, texture coriaceous and without 
_ sculpturing; forewings of female in rest position exceeding apex of ovipositor. 
_ Hindleg with femoral setal formula 2:1:1 or 2:1:1:1, length of first tarsomere 
_ variable compared with combined length of two more distal tarsomeres and 
’ with two parallel longitudinal rows of small setae on plantar surface. 
Male genitalia: Pygofer varying from short to moderately produced, 
_ posterior margin convex and often with a slight concavity in its dorsal portion, 
setae from few to many, mostly on posterior half, often mixed macro- and 
microsetae. Plates elongate triangular, extending posteriorly to varying degree 
compared with pygofer apex, with uni- or multiseriate macrosetae and usually 
with microsetae also. Style extending much farther posteriorly than apex of 
connective, usually without preapical lobe. Connective in form of transverse 
bar. Aedeagus symmetrical, usually expanded apically in caudoventral view. 
Paraphyses absent. 
Female abdominal sternum VII with median posterior lobe which is usually 
rounded apically, acute in some species. Dorsal membrane of genital cham- 
ber often with a conical evagination near base of first valvifer, the structure 
heavily sclerotized and visible externally in some species. Ovipositor with 
second valvulae each narrow in basal portion, apical one-half to two-thirds ex- 
panded and with large dorsal quadrate primary teeth not extending quite to 
rounded apex, apicoventral margin with very fine denticulations. Pygofer with 
very few macrosetae located parallel to apical and to posteroventral margin. 
Specimens belonging to Amblyscarta Stal occur from Mexico to southeastern 
Brazil and northern Argentina, and to Bolivia. Amblyscarta is related to the 
new genera Willeiana, Begonalia, and Gorgonalia. It differs from Wéailleiana in its 
lack of paraphyses in the male genitalia, and it may be separated readily from 
the other genera by its more robust form, and the form of the connective in 
the male. 
The male genitalia of the lectotype of Cicada aurulenta Fabricius agree with 
the illustration published here. A. purpurata (Germar) is placed in synonymy 
through association of Signoret’s (1853b: plate 8, fig. 2) illustration with 
specimens determined as A. aurulenta by the present writer. 
The species Metcalf (1949b:269) identified as purpurata is actually Am- 
blyscarta bicincta (Germar). Signoret (1853b:239) is followed here, as first re- 
viser, in identifying the latter with A. bifasciata (Fabricius), and the present as- 
sociation of the Germar name with the genitalia illustrated here rests on that 
plus a comparison of the genitalia of the male lectotype of Cicada bifasciata 
Fabricius with the present illustration. 
The anterior dorsum of the lectotype of Tettigoniella cervicula Jacobi is like 
the present illustration; the aedeagus is like that of A. bicincta (Germar) (figs. 
155a and 152/); the other genital characters as in the present illustrations of 
A. binotata, n. sp. (figs. 154c-g). 
Metcalf (1955a:264) is followed here in the generic placement of Amblyscarta 
frontaliana Metcalf. A female in the British Museum determined as (A. frontalis 
(Germar)) = frontaliana Metcalf is correctly placed in Amblyscarta, as are two 
females (MMB) and two specimens without abdomens (ZIMH). I have seen 
no other specimens.
